LR9200中文资料LOW NOISE 200mA LDO REGULATOR数据手册UTC规格书

描述 Description

The UTC LR9200 is a typical LDO with the

特性 Features

of high
·output voltage accuracy, low supply current, low ON-resistance, and
·high ripple rejection.
·    During operation of the UTC LR9200, the dropout voltage is very
·low and the response of line transient and load transient are very
·well.
·Internally, there’re many functions of UTC LR9200 which can be
·seen in the block figure. There are a voltage reference unit, an error
·amplifier, resistor-net for voltage setting, a current limit circuit, and a
·chip enable circuit in each UTC LR9200. 
·The UTC LR9200 can be used as an ideal of the power supply
·for hand-held communication equipment, such as: power source for
·portable communication equipment, power source for electrical
·appliances, for example, cameras, VCRs and camcorders and power
·source for battery-powered equipment.
